CARBONDALE prefixes in area code 730
NANPA records 9 assigned NXX blocks to rate center CARBONDALE in area code 730, 6.9% of the 130 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (1), NUSO, LLC (1). The earliest assignment on record here is 2024-04-05 and the most recent 2026-03-09. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 272, 570, 618, 970 – overlay codes cover the same geography, so a rate center is served by all of them.
